SPECIFICATION forming part of Letters Patent No. 381,683, dated April 24-, 1888.

Application filed October 29, 1887. Serial No. 153,715. (No model.)

To aZZ whom. it may concern:

Be it known that we,EDWARD E. EDGERTON and ROBERT METCALF, of Chicago, county of Cook and State of Illinois, have invented certain new and useful Improvements in Vindows, ofwhich the "following is a full,elear,and exact description, that will enable others to make and use the same, reference being bad to the accompanying drawings, forming a part of this specification.

The object of this invention is to provide means whereby access may be conveniently had to all parts of a window for the purpose of cleaning and making repairs; and the sameconsists of certain novel features in the con struction, arrangement, and operation of the several parts, as will be hereinafter set forth, and pointed out in the claims.

Figure 1 is an inside elevation and part-section of the lower half of a window in place, which embodies our improved features; Fig. 2, a detached view of a clamping and adjusting plate; Fig. 3, a vertical sectional detail in the plane 3, Fig. at. Fig. 4. isaback edge view of one of the stiles, showing the relative position of the counterpoisecord and the clamp ing-plate B; Fig. 5, a transverse sectional detail of a portion of the stile andjamb near the top, showing the connterpoise or weight cord and the plate B in section; and Fig. 6, a detached view of a plate which removably se cures the weight-cord to the window.

Referring to the drawings, A represents the lower haif of a window, Athejamb or-frame, and A the sill.

B is a clamping and fastening plate, (see Fig. 2,) which is adj nstably inserted cdgewise in the back of the stiles a a and extends the entire length of the same, as shown in Fig. 1. The grooves in the stiles are of a sufficient depth to receive the whole width of the plate B when the same is retracted to release the window from the jamb. This plate is provided on the edge embedded in the windowstiles with the rounded projections to a a The projection e is in the longitudinal center of the plate, which at this point is provided with the aperture a for the insertion of the spindle or spindles a", on which the ean1-roller a is eccentrically monnted,as shown in Fig. 1. These spindles have suitable hearings in the stiles, the inside ends being square, as shown on the left in Fig. 1, for the reception ofalrey in rotating the same. The plate Bis also provided near each into which projects one end of the riding or hearing pins a the other ends of said being rigidly inserted in the window-stiles. This plate is also provided near the ends with the angular projecting lugs O,asshown in Figs. 2 and 5, the lower half of the plate being broken away in Fig. 2. The outer ends of these logs are bent slightly inward in the direction of the plate, (see Fig. 5,) so as to present an inclined surface and have the functions of a wedge when forced into the jamb and tighten the window against rattling, and also for the exclusion of dust.

end with the curved slots a pins I The stiles a a are provided at each end with the enlarged recess 2) (see Figs. at and 5) for the reception of the angular wedginglugs 0 when the plate B is entirely withdrawn from the janih or frame-work.

b is a sleeve (see Fig. 3) inserted in the stiles a a, at each side of the window,for the reception and movement of the spring locking bolt or catch Z)". The inner end of this belt is provided with the enlarged end b which fills theinner part of the sleeve 2) and engages with the recess 1) in the jamb. The spring 12 coiled around the smaller part of the bolt between the enlarged ends, serves to antomaticall y throw the same into alocking position.

In this improvement the groove 5, forming a passage for the counterpoisecord D, is in the j amb or frame inclosing the window proper instead of in the stiles, as is ordinarily the case, whereby the window may be turned end for end withoutdisconneeting the same from the weightcord.

The cord plate F, Fig. 6, forms a detachable and pivotal connection between the sash-cord and the window. This cord-plate is provided with the rings (Z, securing one end of the sasheord, and is provided in the lower end with the aperture (1, so as to slip over and engage loosely with the end of the sleeve I), extending into the cord'groovc, as shown in Figs. 1, 3, and a.

When the window is to he placed in position, the plate B should be drawn into the stiles by rotating the spindles a", having the cam-roller a. mounted thereon, in the proper direction, then slipping the perforated end of the cord-plate F over the inner end of the sleeve 1) and setting the window in place. Next rotate the spindles a in the right direction to throw one edge of the plate B partially into the cord-groove in the jamb, and as the plate advances the angular lugs on the same will gradually wedge into place'as the camspindles are rotatedand until about the right tension is secured that will permit the window to move up and down freely.

' Ihe plate or plates 13 have a slight endwise or longitudinal movement as well as a lateral one, the endwise movement being limited by the curved slots at and the riding pins a engaging with the same. It will be noted that the plates B may be set so tight that they will prevent the window from rattling.

By having the grooves for the weight-cords in the janib instead of in the stiles, the window may be turned vertically end for end, so

as to bring the outside of the window on the inside, the inner enlarged end of the spring locking-bolts 1) serving as pivots on which the window turns. The weight-cord requires no attention when turning the window, as itoccupies relatively the same position no matter what the position of the window may be.

Thus it will be seen that both sides of the window may be cleaned or repaired with the same facility by a person standing pn the in side, and the opening closed and cold air excluded when the window is in a reversed position. This arrangement not only permits of the outside of the window being made to change place with the inside, but the relative position of the upper and lower half as well, thus bringing the upper half of the window down, when it may be reversed and conveniently reached in the same manner as the lower half.

Only the lower half of the window is illustrated in the drawings; but the upper half will be arranged and supported in the same manner as that described for the lower part. It will be seen, also, that the window may be entirely taken out without removing any portion of the frame-work by simply retracting the locking-plate and slipping the cord-plate off from the sleeve in the stiles.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a window, of the clamping plate or plates 13, provided with the angular lugs O, the central aperture, a, and the curved slots a", the spindle ad, the camroller a, and the bearing-pins a engaging with said curved slots, whereby said plate is adj ustably retained in proper position relative to the window and inclosing-frame, substantially as and for the purpose set forth.

2. In a window, the combination, with the stiles, of the clamping plate or plates B, adjustably inserted in said stiles and provided with the angular wedging-lugs O and the aperture a, the spindle or spindles a having a cam-roller mounted thereon and inserted in said aperture, the pins a and the grooved jambs recessed to receive the wedging-lugs, whereby said plate may be made to engage with or disengage from the jamb, substantially I as and for the purpose set forth.

3. In a window, the combination, with the stiles, of the clamping plate or plates B, provided with the central aperture, a, and having the curved slots of near each end, the cam roller a, working in the opening a, and the riding pins a rigidly inserted in said stiles and loosely engaging with said slots, substantially as and for the purpose set forth.

4:. The combination, with a window and the inclosing-jamb provided with a longitudinal groove, of a clamping-plate provided with the angular wedgingtlugs C, the aperture a, and the curved slots (H, the riding or hearing pins a adapted to engage with said slots, and the spindle having a cam-roller mounted eccentrically thereon and inserted in said aperture to", whereby the rotation of the same adjusts said plate with reference to the stile of the window and the iuclosing-jamb, substantially as and for the purpose set forth.

5. The combination, with a window, of the sleeve or sleeves I), inserted in the stiles of said window and projecting into the sash-cord groove in the jamb, the cord-plate F, loosely engaging with the inner projecting end of said sleeve, and the sash-cord secured to the upper part of said plate, and the lockingbolt b, moving in said sleeve or sleeves and forming a pivot on which the window may be turned, as described, and for the purpose set forth.
